Unit 2: Cell Replication + Meiosis

Question 0

What happens in G1?

Answer 0

Cell grows

Question 1

What is meiosis?

Answer 1

Cell division of the gametes

Question 2

What happens in S?

Answer 2

DNA replication

Question 3

What happens in G2?

Answer 3

Cell prepares for mitosis

Question 4

During what phase does cell division occur?

Answer 4

Cytokinesis

Question 5

During what phase do G1, S and G2 occur?

Answer 5

Interphase

Question 6

What is DNA helicase?

Answer 6

An enzyme which breaks down bonds between bases

Question 7

What type of replication occurs when DNA strands split and form a template for a new DNA strand?

Answer 7

Semi-conservative replication

Question 8

Where do free bases come from?

Answer 8

The food we eat

Question 9

Which enzyme links the nucleotides?

Answer 9

DNA polymerase

Question 10

What happens during interphase?

Answer 10

No cell division

Question 11

What happens during prophase

Answer 11

The chromosomes condense, the nuclear envelope disappears and the spindles begin to form

Question 12

What happens during metaphase?

Answer 12

The chromatids attach to the spindle fibres and they line up along the equator

Question 13

What happens during anaphase?

Answer 13

Spindle fibres contract and centromere splits, one pulled to each pole

Question 14

What happens during telophase?

Answer 14

The cytoplasm divides and the nuclear envelope reappears, the spindles disintegrate and the chromosome begins to uncoil

Question 15

What’s an allele?

Answer 15

One form of different genes
